Manas Petroleum Corp. (OTC.BB: MNAP) has signed a MOU with a Mongolian
company, Shunkhlai Energy, regarding petroleum exploration in block XXIII.
Manas Petroleum has a right to purchase a 90% interest in the Mongolian
company, which has won a bidding round for the block XXIII.

Block XXIII is situated in the Gobi desert in the southern part of
Mongolia bordering China and totals 18,091 km2 (4.47 million acres) of highly
prospective oil-bearing area (outlined in red on attached map). Across the
border in China (Inner Mongolia Autonomous Region in North China) the Gobi
desert is known as one of the major producing regions of China.

Block XXIII is located in this oil bearing province and has multiple oil
seeps where reservoir rocks outcrop. The same reservoir rocks are producing
oil in Zuunbayan and Tsagaantsav shallow oil fields which are situated in
close vicinity to the north of block XXIII. The oilfields are operated by a
Chinese company Dong Sheng, which is a branch of PetroChina, which operates
in the north of China and in Mongolia. The two producing oilfields are very
shallow (a few hundred metres deep). To the south in China's Inner Mongolia
Autonomous Region is a large natural gas field discovered by PetroChina. The
field is currently estimated to contain over 600 billion cubic meters (21.18
trillion cubic feet) of natural gas and 500 million tons (3.6 billion
barrels) of oil.

Large structures have been identified by old Soviet seismic acquired
within Block XXIII during the 1970s. The structures are situated beneath
regional thrust faults and may entrap large volumes of hydrocarbons in the
same reservoir rocks which produce hydrocarbons in the upper thrust sheet
close to the surface.

In July 2007, field work performed by Manas Petroleum in the territory of
block XXIII, confirmed the structural model and also indicated the presence
of large thrust-related prospects throughout the block.
